The 33-year-old Francis appeared in nine games for the A’s (all relief appearances) and yielded nine runs in 13 1/3 total innings with a 10-to-3 K/BB ratio. The longtime Rockies hurler began the year with the Reds but was claimed off waivers by Oakland back in May. Once a mainstay in Colorado’s rotation, Francis has seen his stock drop since his peak years in 2006-07. The former No. 9 overall pick in the draft has a career 4.95 ERA with 6.0 K/9, 2.7 BB/9 and a 44.6 percent ground-ball rate in 1267 1/3 innings.

O’Flaherty will be making his first appearance on Oakland’s active roster after signing a two-year, $7MM contract with the A’s this offseason. The former Brave underwent Tommy John surgery last year and has been on the shelf all season as he recovers. When healthy, O’Flaherty was one of the National League’s best setup men, posting a 1.99 ERA with 7.2 K/9 and 2.9 BB/9 in 249 1/3 innings from 2009-13. He’s lethal against opposing lefties and has typically been solid against right-handed hitters as well, so he will make a nice addition to Oakland’s relief corps.
